语言追求简练，这是两个介词后省略宾语的结果。在 in 之后可能省略了表示“时间、地点” 的名词；在 between 之后可能省略了其他相应的名词，都可以根据上文补充完整。

按照省略前的分析即可。如果按照省略后分析，只能是出力不讨好。

把以下两组句子的来龙去脉弄清楚即可。要想知道第3句的意思，看上面两句：

1. The city lies in a place between New York and Chicago.
2. The city lies in between New York and Chicago.
3. The city lies in between.

1. He has breakfast and supper and doesn’t eat anything in any time between them.
2. He has breakfast and supper and doesn’t eat anything in between them.
3. He has breakfast and supper and doesn’t eat anything in between.
